'lhis invention relates to improvements in change making machines and more particularly to a mechanism for the purpose which is of simple, compact design arranged to receive coins ot different denominations and to deliver a plurality of coins or tokens of a smaller denomination, aggregating in value, the value of the coininserted;

A further object is to provide a change maker in the form of a self contained unit adapt-ed to be operated entirely independent of any vending or other machine requiring coins of a certain size or denomination to operate the same in delivering merchandise l5 or service, such as those machines which are commonly provided for the general use of the public.

It is also an object to provide a mechanical unit for the purpose, which may be used 39 as an accessory to be built into, or attached to existing types of coin operated vending or service dispensing machines, as a convenient source of the required size of coin or tollen for the operation of such machines.

For the purpose of brevity in the description, I will refer hereinafter to the various sized coins, as quarters, dimes, and nickels as being the coins which the present embodiment is designed to handle,.but it is to be understood that the use ot these terms shall not be considered as limiting the device to the employment otcoins of these particular denominations, since, to adapt the 5 device to use domestic coins orn other sizes a or to foreign coins, would only involve changes in dimensions of certain mechanial parts and would not affect the general construction.

The present embodiment of this invention is disclosed in detail in the accompanying drawi, cfs in which- Figure l is a front elevation of a device illustrative of an embodiment of the present invention, with a key coin receiving mechanism shown in its neutral position;

FiG. 9 is a detail, the same as that of Figures 7 and 8, with these parts in the neutral position las shown Figure 1 Figa-10 is a transverse vertical section on the lines F-F of Figures 6 and 11, showing coin discharge mechanism and actuating means as arranged in the casing; and

Fig. 1l is a horizontal section upon the line D-D of Figures l0 and 6.

-ln general,the device consists of two coacting groups of elements; the coin receiving group and the coin discharge group, the two groups being arranged to cooperate when aproper coin is inserted tol serve as a key or driver to operate the discharge mechanism when the coin receiving mechanism is operated.

For the sake of clarity I will describe the groups, one at a time, first taking up the coin receiving mechanism. Acoin of the proper denomination is insertedin one of the corresponding openings l or@ in a front cover plate 6 of asuitable casing 6 yuntil it rests against a plate 3 secured between said plate 6 and the casing front wall. Grooves or slots el and 5 are cut in the back of said -front cover plate 6 leading from said openings 1 and 2, respectively, to provide guideways to convey the coins by gravity to the positions or y, where itis in a position to serve asa keybetween a driver or abutment 7 integral with the back of a driver plate 12 and an engaging lug 8 or 9 on plat-e 10, it being caught and stopped between these parts.

The openings 1 and 2-and grooves 4 and 5 are accurately machined to allow the least practical clearance around a newly minted coin in order to protect the entire device from the insertion of impropendamaged or counterfeit coins or slugs and to avoid cheating, or the jamming of the mechanism.

- l/Vith a coin in a key position or y, when the handle 11 is turned in the direction of the inserted coin, the various parts assume positions shown in Figures 3 or 5 as the case may be. The driver '7 forms an integral abutment onl plate 12 which is retained and keyed to the handle llbymeans of nut 13 and dowel 14, and the shaft 15 is an extension of the handle 11. Tofprevent moving the handlek the wrong way or away from the inserted coin, a stud 16 is set into the back'of plate 6 so as to be engaged by the coin as it is carried Varound by the turning of the handle and stop such movement by the jamming of the coin between this stud 16 and one of the vlugs 8 or 9. The rocker plate 10 is pivoted to an arm 17 mounted to turn upon the shaft 1,5, by means of aloose rivet 18 so that when the coin drives the plate 10 to one side or the other, the arm 17 `is rotatedupon said shaft 15 to approximately one or the other of the positions indicated in Figures 3 and 5, and. this movement serves to actuate the coin discharge device, as hereinafter set forth. v n

Vhen the coin reaches the positions a or (Figures v3 or 5) the lug 8 or 9 which h as been held in engagement with the coin by contact against a circular guide" surface 21 on plate 3, now falls away from the coin as it reaches the end of the circular pathway, thus permitting the driver 7 to advance a little farther and so eject the coin into the tray 22a. c Figures 3 and 5 show coins atthe point of falling away. Y v l As soon as the coin falls, the handle and all of the parts connected theretoand actuated thereby, are returned to neutral position shown in Figure 1, ready to be again operated. 4This return movement is effected by means of spring loaded parts attached to the rear endportion of shaft 15, and consist of a cam 22 secured to the shaft 15 by a screwed stud 23 which is extended to form a leverto the upper free end of which is attached one end ofa pull spring 24, the opposite orupper end of which is anchored to a rigid arm 25 on the casing 6. These parts are shown partly in section in Figure 6 and in elevation in Figures 7 and 3 with said parts in their extreme positions of movement, said spring 21 acting on the lever 23 exerting a force to return the shaft and connected parts to approximately-neutral'or intermediate position after manual operation.'v

In order to further insure an accurate neutral position, a spring loaded plunger 26 having a lateral stud 27 is provided, so that said stud is .caused to ride upon the surface of said cam 22 which is formed with a deep depression or notch 27a intermediate its ends, into which said stud drops to insure centralization of the parts' andto hold these partsV yieldinglyin neutral position' as shown in Figure); n Thefmechanism for discharginga `certain number yof 'coins' in exchange for either the coin 1 or 2 inserted and of an aggregate value equal to the value of the'inserted coin', comprises arec'iprocating slide 23 having holes 29 and 30 la'rramged to receive coins from a'magazine or tube 31 down which they, arefedby gravity, said slideA being ar! ranged to receive a numbe'rofcoins through said holes therein and'move these coins siderise'until they: 'are permittedito fall voutfof said slide 23 by gravityinto a surrounding hopper 32 which 4is arranged 'to'convey them to a delivery pocket 33 where thel operator may takethemfo'ut with his fingers.

Y Reciprocating movement of `said slide' 23 is `r effected by an oscillating motion of said arm'17 (as Vprevieusly described) which motion is transmitted throughagear 341 to a rack v35 secured tothe bottom of saidl slide 28. A cam 3 6 is secured by screiws37jand dowels 38 .to turn,` with said gear S4-"and 4arm 17, this f assembly Abeing freely'rotatable: 'on the shaft`15, and thiscam 36 is formed with surfaces 39and 3960,4"one surface, 39a being at a greaterradial distance from theaxis' of the cam, than the surface 39, thiscambeing arranged with its' `e;`\te`rn'al cam surfac'edfirectly below the lowerend of: the' magazine tube31- andV of aywidth equal to or greater than the diameter of said tube, so that coins dropping into lthefhoies29 or 30'A in lsaidy slide 28will rest uponI said cam surfacevand be` supported thereby until slid laterally therefrom by the endwise movement of. said slide.- Thenumber of coins which willdrop down from said magazine tube is determined by the position of said` cam 36, as a greater number will be discharged when the surface 39is opposite the magazine, than whenthe surface 39a is uppermost, and `as ,the posi- 4: tion of said cam is determined bywhichwdevnomination ofcoin is.` insert-ed inthe respective openings 1 or 2, the proper surface 39 or 39a will bein position topermit the right number of coins to dischargefrom thle'maga- Zine m exchange for the inserted coin. Figure 7 shows the cam 36 in position to permit `the escape of ive coins, and in Figure 8 said cam is shown in position to permit ythe discharge of two coins only. In Figure 9, said slide 28 is shown in mid or neutral position with both of the said holes 29, 30 out of alignment with the stack of coins in the magazine Vand supporting the entire stack, all of the parts of the machine being in inoperative or neutral position.

Gn the slide 28 are ormed guards 40 and 4l at opposite sides of the openings 29-30 therein to engage the stack of coins discharged from the magazine 3l and hold these coins in position while being supported by the cam 36' and prevent them from tilting in a manner to disturb the other coins'in the magazine or sliding from the cam surface while being moved bythe slide. Having discharged the desired number of coins, said slide is returned to neutral position by the action of the spring 24 which also turns said cam 36 to neutral and in position to support the stack in the magazine. The movement ot the slide to eXtreme position in either direction, moves the coins taken from the magazine, out of Contact with said cani and permits them to drop into the discharge hopper 32, from which they may be readily taken as change for the inserted coin.

To aid in returning said slide 28 and parts operatedin unison therewith to neutral position, springs 42, (See Figure 10), are positioned to act against its ends within slots 43 in said ends, said springsbeing secured to the-opposing "walls of the casing 6, and to eect complete and exact centralization of said slide, a plunger 44 having a wedge shaped lower end, is guided for vertical movement in an opening in a bridge bar 45 to engage within an angular notch 47 cut in the edge of slide 28. A spring 46 sleeved on the stem of said plunger, normally urges the wedge shaped lower end ofthe plunger into said tapered opening in the slide and yieldingly holds said slide in exact position. All lost motion of the co-acting parts is thus eliminated so that theyV will come to their exact relative positions and when a key coin is inserted, said slide will be moved by the manual operation of the handle l1 to bring one of the holes 29 or 30 into exact alignment with the lower end of the magazine 3l to receive the desired number of coins therefrom to make change for the inserted or key coin.

A very simple and compact arrangement of change making mechanism is thus provided and which mechanism comprises a complete unitary structure which may be used independently or may be embodied in another machine as desired. Further, the construction is suchV as to eectually guard against the use of slugs or bad coins,-a.nd

the device is simple to operate and not liable to get out of order.
